CASH AND AUTOGRALPHIC REGISTER.

Specification of Letters Patent.

' Application filed March 9, 1910. Serial No. 548,173.-

Dayton, in the county of Montgomery and State of Ohio,have inventedcertain new and useful Improvements in Cash and-Autographic Registers,of which I declare the following to be a full, clear, and exactdescription.

This invention relates to cash registers and among the objects of theinvention is to provide an improved autographic attachment to cashregisters and the register controlling means for printing upon strips ofautographicpaper the amounts of items which are recorded in theregister.

Another. object ofthe invention is to provide separate connections fromthe driving mechanism of the cash register for feeding the autographicpaper.

Another-obj'ectoflthe invention is to provide a combined cash registerand auto-' graphic device with a sin le means for operating the drivingmechanisms of the two devices which means may be adjusted to cause theoperation of either the cash register or the autographic device at will.

Another object of the invention is to provide a cash register with meansfor printing records upon strips of autographic paper combined withmeans for prlnting upon a strip of check paper.

Another object of the invention is to provide a cash register withcombined means for printing upon a strip of autographic pa-- per and astrip of check aper with a manipulative device for ma 'ng-the printingmechanism inoperative and with means depending upon-the-manner ofoperating the machine for restoring the printer to its operativecondition.

vWith these and incidental objects in view the invention consists incertain novel features of construction and combinations of parts theessential elements of which are set forth in appended claims andapreferred form of embodiment of which is hereina fter described withreference to the drawings which accompany and form 'part of thespecification. i

device upon any or all operations of the machine. v

The cash register to which the present improvements areshown as appliedis a well known machine which is fully described in tive or inoperativeby a manipulative device condition before the special transaction isrecorded.

The cash register comprises a plurality of banksof value keys, each bankcontrolling a denominational element of differential mechanism which isin turn geared to a pinion having secured thereto a type-carrier of adenominational order corresponding to the denominational order of itscontrolling element in the difierential mechanism. Therefore the settingof the type-carriers corresponds to the operation of the differentialmechanism which is controlled by the keyboard of the cash register. Thetype-carriers are provided with two like sets of type, one set forprinting upon a check strip and the other set for printing upon stripsof autographic paper. A consecutive numbering device is journaled at theside of the type-wheels and also bears two sets of type for printing onthe check'strip and the autoraphic strips so that the consecutive numherof each record will be printed at the side ;of the record. The platensfor taking impressions. from the type-wheels are operated during theoperation of the cash register and just before the cash register comesto rest. The feeding mechanism of the autographic device maythen beoperated to feed a slip of autographic paper out of the autographicdevice and also.roll up a duplicate of such slip within the autographicdevice. The platen for causing impressions to be made upon theautographic strips is so arranged that it may be prevented fromoperating regardless'of what kind of transaction is recorded in theregister, while the check printing mechanism may be made inoperativeonly upon the recording of cash sales.

To operate the machine, the desired amount keys are depressed and thenpower is applied to the. driving mechanism by means of a crank handle 1(Fig. 5) which is rotated twice thereby causing a pinion 2 to make tworotations and as it is normally geared to a gear 3, of four times itsdiameter, the gear 3 will make one-halfof a rotation. The gear 3 througha train (Figs. 4 andl3) of gears 4, 5, 6, 7, 705, 8, 9, 905, 10 and 11causes the desired rotation of the operating elements of the checkprinting device and operation of a platen '12 of the autographic device.The gear 4 also meshes with a gear 13 which is secured to the main driveshaft 14 of the cash register.

The platen 1201? the autographic device and a-platen 15 for the checkprinting mechanism are operated by cams 16 (Fig. 11) and 17 (Fig. 9)respectively, but these cams do not operate the platens until amounttype-wheels 18 have been properly set by the register. The cams 16actuate the platen 12 by co-acting with rollers 19 which are carried byarms 20 rigid with the platen 12 and when the shoulders 21 of the cams16 clear the rollers 19, the platen will be drawn by a spring 22 intoengagement with the type-wheels 18. The platen 15 is suspended from arms23 which are pivoted on a shaft 24 by the links 25 and is guided to movein a vertical direction by guides 26 and 27. The shaft 24 upon which thearms vto rock far enough so that the platen 15 will engage an ink padholder 37 pressing the same against the type. and thereby inking thetype. The platen is then returned to its normal position and when theparts 36 of the grooves in the cams 17 engage the roller 32, the platenwill be lowered again and far enough to cause an impression to be madeupon a strip of check paper 38.

The ink pad carrier 37 is pivoted on pin 39 to an arm 40 which ispivoted concentrically with the type-wheels 18 and is rocked to carrythe ink pad holder 37'beneath the platen 15 by a pitman 41 before thefirst lowering of theplaten 15.- The pitman- 41 is operated by a cam 42which co-acts with a roller on the pitman for the purpose of 0scillatingit.

The check paper 38 is led from asupply roll (not shown in the drawings)through a guide 44; between an electro-roll 45 and an impression roll46; through a guide 47; between an electro-roll 48 and an impressionroll 49; from thereout through guides 50 and 51; between the type-wheels18 and the platen 15, and finally out through an opening 52 in a casing53. When the platen 15 is lowered to take. an impression the printedportion of the check strip 38 is severed by a knife 54 which is securedto the platen 15 and co-acts with a fixed knife edge 55. The

electro-rolls 45 and 48 are on opposite sides of the check strip 38 sothat one of the rolls will-print upon. the face of the check strip upon,the check which is to be issued on a coincident operation as is the casewith the amount type-wheels 18.

The platen 12 which causes impressions to be made upon strips ofautographic paper 56 and 57 operates after the amount type- Wheels 18have been properly set and before the crank handle 1 comes to rest.After the crank handle comes to rest it is drawn outwardly to carry thepinion 2 (Figs. 3 and 5) which is rigidly secured to a sleeve 58 uponwhich the crank handle is mounted into engagement with a gear 59. Thecrank handle 1 is then given one rotation thereby causing the gear 59 tomake one quarter of a rotation and the gear 59 meshes with a gear 60(Fig. 1) which in turn meshes with a pinion 61 meshing with the gear 62which meshes with a pinion 63 and through an intermediate gear drives apinion 64. The pinion 63 is secured to-a feed roll 65 which throughfriction engagement with a roll .66 feeds the autographic strips 56 and57. The stri 56 is led out of casing 67 of the autograp ic device at 68and the strip 57 is led from the rolls 66 and 65 to a receivin roll 69to. which the pinion 64 is secured. tolls 7 0 and 71 are the supplyrolls of the strips of paper 56 and 57 respectively. If it is desired tomake autographic notations of a sale which is to be recorded in theregister these notations will be made upon the strips 56 and 57 at thewriting space 72 before the second operation of the crank. The writingplatform 7 4 has hinges 75 and rests upon lugs 76. In order to removethe autographic strips, the casing 67 has hinges 77, and by rocking thecasing, and then rocking the table 74 around its hinges 7 5, the storageroll may be removed. Access to the supply rolls 70 and 71 is had byremoving the usual hood 53 which surrounds the printing mechanism. Thishood is held in place by lugs and a lock co-acting with shoulders on theframe 78, but these are not shown in the drawings.

The ink for the impressions on the strips 56 and 57 from the type-wheels18 is furnished by an ink ribbon 79 (see Fig. 10)

which is an endless ribbon supported by rolls 80 and 81 and passing overthe strip 56 and over the strip 57. The roll 81 is furnished with aknurled head 82 (Fig. 3), by which it may be manually rotated to feedthe ink ribbon.

The rolls 45 and 49 are journaled upon eccentric disks '83 and 84 whichmay be slightly rocked to carry the rolls 45 and 49 away from the rolls46 and 48 thereby preventing the feed of the check paper and alsoimpressions thereon both from the rolls 45 and 48 and from thetype-wheels 18 as when the rolls do not feed the strip of check paperthe strip will not be moved between the platen 15 and the type-wheel 18.The eccentric disks 83 and 84- may be rocked to cause the printer tobecome inoperative by a knurled head 85 which is mounted upon the shaft86 carr 'ng the disk 84 as illustrated in Fig. 1'2. he shaft 86 carriesan arm 87 to which is pivoted a link 88 connecting the arm 87 with anarm 89 secured to a shaft 90 which carries the eccentric disk 83.Therefore when the shaft 86 is rocked, the shaft .90 will also rock,thereby causing the rolls 45 and 49 simultaneously to rock away from ortoward their companion rolls. A link 91 connects the arm 87 with an arm92 which is secured to a shaft 93. This shaft carries an arm 94 (Figs. 1and 2) which when the cocentric disks 83 and 84 are rocked to carry therolls 45 and 49-away' from their companion rolls, will because of thelink connection 91 rock into the path of a rearwardly extending arm 95of the arm 20 which rocks with the platen arm 12. It is thereforeimpossible for the platen 12 to operate when the check printingmechanism ismade inoperative.

The slot and pin. connection between the knurled head 85 (Fig. 12) andthe shaft 86 permits the shaft 86 to oscillate to cause the checkprinting mechanism and platen 12 to become operative independently ofreturning the knurled head 85 to its original position and the shaft 86may be so rocked by depressing one of the special keys 96 (Fig. 8). Themachine is arranged to compel the issuing of a check regardless of thesetting of the knurled head 85 whenever one of the special keys isdepressed, as one of these keys is depressed whenever a Received onaccount, a Charge or a Paid out "transaction is recorded and the checkin such cases serves as memorandum of the transaction. It is also attimes particularly desirable when such records are made to issue. anauto-v graphic sales slip; For this reason, the autographic mechanismisarranged to become operative whenever the check printing mechanism isoperative. To this end the special keys 96 are depressible against theaction of s rings and are guided by a slotted plate 9 the slots of whichco-act with pins 98 on the special keys. These pins extend beyond theplate 97 across, the edge 99 of a slide 100' which when a special key isdepressed moves rearward in a lineal direction against the action of aspring 101. At its rear end the slide 100' is provided with an angularopening 102 through which extends a pin 103 carried by an arm 104 se-.cured to the shaft 93. When the slide 100 upwardly upon the depressionof a special key it rocks the shaft 93 thereby causing the arm 94(Fig. 1) to move away from the extension 95 of the arm 20 and alsothrough the arm 92, link 91, and arm 87 causes the eccentric disks 84and 83 to rock their respective rolls into contact with their companionrolls thereby making the printing mechanism operative. The special keysare retained in their depressed position, while the machine is operatingby any usual key detent. After the release of the depressed special keyand when the machine comes to rest in its home position, the slide 100is returned to its initial position by the spring 101 and the spring1061 returns the arm 104 and the mechanism which the arm 104 controls,including the eccentric disks, to their original positions. During therotation of drive shafts of the machine slide 100 is retained either inits outer or inner position by a circular flange 200 co-acting with. a:

roller 201 of the slide.

The knurled head 85 (Fig. 12) engages shaft 86 by a pin 126 extendinginto a groove 127 in the shaft and is retained in its set position by afixed pin 128 which coacts with holes 129in the head 85. The shaft 86 ispartly cut away at one side of groove 127 thus permitting the shaft to'rock in one direction independently of the knurled head. Thisarrangement is provided so that when the eccentric disks are circularrace in a disk 134 through an open-' ing 135 therein. The shaft 136 towhich the disk 134 is secured carries a gear 137 which meshes with agear 138 rigid upon the shaft 14. Therefore upon'the rotation of theshaft 14 the disk 134 will berotated and through the arm 131 willpositively.

hold the check printing mechanism either in its operative or inoperativeposition depending upon whether the roll 133. is outside of the disk 134or in the race thereof.

Fig. 2 illustrates a modification of .the mechanism for making theplaten 12 inoperative which operates reversely to that which is shown inFig. 1. If the machine is constructed with this modificationit willresult in the platen 12'' becoming inoperative when the check printingmechanism is made operative and'vice versa. The object of thismodification is merely to provide means if memes described.

The gears 3 and 5 9 are provided with guards 107 and 108 respectively(Figs. 5, 6 and 7). The gear 3 makes one-Half of a rotation upon eachoperation of the machine. At the completion of the operation, the operator may wish to operate the autographic v mechanism. He will thenpull the handle 1 outwardly drawing the pinion 2 through one of the cutaway parts 109 in the guard 107 and through one of the cut away parts110 in the guard 108 into mesh with the gear 59 by means of which theautographic mechanism is operated. When the handle 1 is drawn outwardly,a disk lll which is carried by the sleeve 58 to which the handle 1 issecured enters one of the cut away parts 109 of a disk 112 which issimilar to the disk 107 and also rigidly secured to the gear 3. Itistherefore impossible to rotate the gear 3 when the pinion 2 meshes withthe gear 59. Also when thehandle 1 is in its inner-position, the disk113 enters one of the cut away parts 110 of a disk 114 which is aduplicate of the disk 108 and is rigidly secured to the gear 59. Thusthe gear 59 is prevented from rotating while the cash register is beingoperated. The disks-107 and 112 are provided-with two cut away parts atopposite sides of the disks because these disks only make one-half of arotation upon each operation of the register. The disks 108 and 114 areprovided with four cut away parts 110 equally spaced from each other asthese disks only make one-quarter of a revolution upon each operation ofthe autographic. mechanism.

When the autographicfeed' takes place the handle 1 is stopped in itshome position and pinion 2 again meshed with gear 3. The sleeve 58 whichcarries pinion 2 and disks 111 and 113 is urged to its inner position bya spring 125 (Fig. 5). Accordingly when pinion 2 is in mesh with gear 59the spring 125 serves'to carry pinion2 out of mesh with gear 59 and intomesh with gear 3 upon the completion of a rotation of pinion 2, at whichtime one of the cut away parts of disk 114 registers with disk 113.

At the left side of the type-wheels 18 are four type-wheels 115 (Fig.3-) which are similar to the amount typewheels 18 but are usedforprinting a consecutive number upon the check and autographic strips.Impressions are taken from. these type-wheels by the same-platens.-12-and 15. The typewheels 115 are loosely journaled upon a sleeve 116and are normally prevented from rotating by retaining pa'wls'117 whichare spring pressed into engagement with notched disks 118 rigid with thetype-wheels 115. The consecutive numbering device is operated by amultipronged pawl 119 which is carried by an arm 120 journaled upon thesleeve 116 and provided with an ear 121 whereby it is pivoted to one endof a pitman 122. Thepitman 122 is reciprocated to rock the multiprongedpawl one tooth space upon each operation of the machine by a box cam 123acting upon a roller 124 carried by the pitman.

Fig. 14 shows a hand operated device which may be employed to preventthe platen 12 from striking, if it is desired not to print on theautographic strip. Its operation is obvious.

check strip. The same movement of the eccentric disks draws link 91upwardly and through it moves the stop 94 into the path of the extension95 of the platen arm 12 and thereby prevents operation of the platen ofthe autographic device. In operating the register in this way aftertwice rotating the handle 1, the handle 1 will not be drawn outwardly asis the case when the autographic device is operated. If the printingmechanism is in its inoperative condition and a special transaction isrecorded the depression of one of the special keys 96. will cause theprinting mechanism to become operative and thereby issue a check andalso print the record upon the autographic strips. The

depression of one of the special keys by pushing the slide 100rearwardly causes the shaft 93 to rock back to its normal positionOperation: When a cash sale is recorded erated as follows: The amountkeys repre-.

senting the amount of sale are depressed and then the handle istwicerotated causing the register to be operated as controlled by thedepressed amount keys and thereby through the pinions 185 set up thetype Wheels 18. At the same time the check strip 44 is fed forwardly bytwo pairs of rolls 45 and 46 and 49 and 48, these rolls at this timeprinting the date and any other desired matter upon the front and theback of the check strip; The platens 12 and 15 are then operated, theplaten 15 effecting the impression from the amount type wheels and theconsecutive numbering device upon the check strip 44, and also, as itcarries the knife 54, cutting the printed part of the check from theremainder of the strip. The platen 12 serves to cause the same record tobe printed upon the strips of autographic paper 56 and 57. The handle 1is then drawn outwardly and caused to make one rotation. Writtennotations are made upon the autographic strips at the writing space 72before the handle 1 is drawn outwardly androtated. Upon this secondoperation of the handle 1, the printed part of the strip 56 is fed outof the autographic device at 68 and the duplicate is rolled up on theroll 69. The feed rolls 65 and 66 are caused to rotate at this time bythe train of gears 59, 60, 61, 62 and 63 which serve to transmit therotation of the pinion 2 to thefeed rolls 65 and 66. 7

If when a cash registration is made it is not desired to record the saleupon the check strip 44 and the autographic strips 56 and 57, the knob85 (Fig. 4) is rocked to the right, thereby causing the eccentric disks83 and 84 to carry their respective rolls 45 and 49 out of contact withthe companion rolls and thereby prevent the feed of the and through thelink connection 91 with the disks 83 and 84 causes them to rock theirrespective rollers 45 and 49 into contact with the companion rollers.Then when handle 1 is rotated the check strip 44 willbe fed, forwardlyand printed and the autographic strips will also be printed. Upon therelease of the depressed special key, the shaft 93 will rock to theposition where it prevents operation of the printing mechanism under theaction of the spring 106.

While the form of mechanism here shown and described, is admirablyadapted to fulfil the objects primarily stated, it is to be understoodthat it is not intended to confine the invention to the one form ofembodiment herein disclosed, for it is susceptible of embodiment invarious forms all coming iwithin the scope of the claims which fol- Whatis claimed is:.
